How did Acadian settlers make Bay of Fundy marshlands suitable for farming?

Acadian settlers transformed the marshlands along the Bay of Fundy into productive agricultural land beginning in the mid-17th century by constructing dikes.1

These settlers utilized dikes to reclaim coastal areas by blocking the entry of seawater, which allowed the land to be drained and cultivated. This process was essential for creating fertile fields in an area otherwise dominated by high tides and salt-affected marshes. By effectively managing the water levels through these engineering efforts, the Acadians successfully converted thousands of acres of marshland into valuable farmland.213
